HVAC filtration part of a COVID-19 protection strategy

COVID-19 HVAC Protections

G&B Environmental, Inc is committed to providing our clients with the most recent information for helping them select the right products to protect their employee’s and family members during the most recent COVID-19 Pandemic.  According to ASHRAE Journal Newsletter, March 24, 2020:

Basic principles of social distancing (1 to 2 m or 3 to 6.5 ft), surface cleaning and disinfection, handwashing and other strategies of good hygiene are far more important than anything related to the HVAC system.7 But, once those basics above are covered, they have a few recommendations for HVAC systems:

  • Increase outdoor air ventilation (use caution in highly polluted areas); with a lower population in the building, this increases the effective dilution ventilation per person.
    • Disable demand-controlled ventilation (DCV).
    • Further open minimum outdoor air dampers, as high as 100%, thus eliminating recirculation (in the mild weather season, this need not affect thermal comfort or humidity, but clearly becomes more difficult in extreme weather).
  • Improve central10 air filtration to the MERV-1311 or the highest compatible with the filter rack, and seal edges of the filter12 to limit bypass.
  • Keep systems running longer hours, if possible 24/7, to enhance the two actions above.
  • Consider portable room air cleaners with HEPA filters.
  • Consider UVGI (ultraviolet germicidal irradiation), protecting occupants from radiation,13 particularly in high-risk spaces such as waiting rooms, prisons and shelters.

We all have a role to play to control the spread of this disease. HVAC is part of it and even more significant are social distancing, hygiene and the influence we can have on personal behavior.

Sanitation tip for Restaurants & Bars that are shut down: Run your taps, clean water filters, watch for microbiological growth

For Restaurants, Bars and Service Technicians out there that have had business slowed or shutdown; we have some useful information regarding what you should be doing with water applications and your filtration systems in shutdown restaurants during this pandemic.

If you have not had water running through your water filtration equipment in the past week for example you will want to flush water through your filters ASAP. Followed by flushing your water filters every 3-4 days to maintain the life.

If however, you have gone past 7 days since having water run through your filters and food service equipment you may have other issues. For example in this scenario it has been determined that microbiological growth can occur within the filter cartridges past 7 days. Water filters are meant to have water running through them continuously without stop with exceptions only to weekends and long holidays (per manufacturers). If this is the case you will unfortunately have to replace your current water filter cartridges and sanitize your filter head and equipment the filters were leading to.

Please call us to receive the latest information 1-800-466-2018.

April 6th 2020 Starting to clean commercial air conditioning systems in Minnesota.

Contaminants in the heating and cooling system cause it to work harder and shorten the life of your system. Although filters are used, the heating and cooling system still gets dirty through normal use.  When an HVAC system is clean, it doesn’t have to work as hard to maintain the temperature you desire. As a result, less energy is used, leading to improved cost-effectiveness.  We were out today cleaning refrigeration / HVAC condenser coils and intake filters at an essential food processing facility.  Please call early to get on the schedule this year.  We are open and working during these unpresented times. 1-800-466-2018

Negative pressure rooms: an intro for operations and facilities managers

It seems like every day we’re learning something new about coronavirus and how to combat it. Luckily we’re not learning it from scratch. The National Air Filtration Association (NAFA) has guidelines and recommended practices for filtration for airborne infections containment rooms in health care facilities. Initially designed for diseases such tuberculosis, the process and system is well documented and aligns with protecting against COVID-19.

It starts with the negative pressure rooms. The idea is to keep infectious particles from leaving the room. Air removed from these rooms is filtered or exhausted outside to insure that infection is not spread from room to room. And NAFA guidelines call for this happening 10-12 times per hour.

Properly installed, sealed and tested HEPA filters are integral to the process, especially when there are space issues pushing the air outside. You’ll want to get someone who is trained and certified to work with the HEPA filter. Choosing the right installer is as important as choosing the right filter.

G&B Environmental technicians can help you choose the right filter for your location and need:

Clean vents won’t help with Coronavirus but UV light services will

G&B clean coils specialty

G&B Environmental HVAC, Ducts, UV light…

We are getting calls about vent and duct cleaning to protect clients and their staff from Coronavirus. Unfortunately, while cleaner vents and new filters can help create a healthier environment they can’t stop micro-organisms in the Coronavirus. Microscopic allergens and other contaminants travel through the ducts in your HVAC system; they are too small to to filter out.

How does UV Light work?

Hospitals use UV light to disinfect equipment. Some are looking at using it to clean whole rooms. But UV light will burn your skin and retina. So the rooms must be empty during the process. We can help with this level of protection if you want it, but for most homes and businesses that is impractical. So we work through the HVAC system.

Ultraviolet lamps will kill airborne germs and organisms. The UV-C light disrupts their DNA, leaving them unable to perform vital cellular functions and causing them to die. That is essential because the coil stays wet for several months during the year and microorganisms, including mold, typically thrive in a wet environment.

A UV light unit is installed in the return air duct and cycles on with the air handler blower.  A complete UV light unit sterilizes moving air itself as it is pushed through the HVAC system. This treats the air that is contaminated by any number of sources. Learn more on how UV lamps work.

They work! But they don’t work alone and UV air purifiers installed in the HVAC system cannot guarantee that your family or staff will not infected by the virus.

What else can you do to keep your team safe?

Ultraviolet lamps can keep the air cleaner, but just as doctors wash their hands in the hospital, your staff will need to take everyday precautions as well. The Center for Disease Control and Prevention released guidelines to help you keep your office healthy:

  • Actively encourage sick employees to stay home
  • Separate sick employees
  • Emphasize staying home when sick, respiratory etiquette and hand hygiene by all employees
  • Perform routine environmental cleaning

Keep calm
We all want to keep our families, friends and staff safe and happy. A little common sense and some UV-C technology will help!

Call us at  952-469-3024 of or check out the website for more info on how it works.
